BRONZING APPARATUS.

Application filed ctober 17, 1917.

To all whom t may concern.'

Be it known that I, FREDERICK GILBERT, a subject of the King of Great Britain and Ireland, residing at Arthur House, Wellington Road, Edgbaston, Birmingham, England, have invented certain new and useful..

Improvements in and Relating to Bronzing Apparatus, (for which I have applied for a patent in Great Britain, No. 108,956, bearing date 28th October, 1916,) of which the following is a specication.

This invention, which is an improvement upon or modification of that described in the prior Letters Patent of the United States, No. 1,105,508 granted to me July 28th 1914, relates to bronzing apparatus comprising a portable bronzing head, which embodiesl a receptacle or container for the powder, having at its underside adjustable openings or outlets, and a pad of felt or wool, or other soft material; the said container being inclosed or surrounded by a hood or cover, the underside or rim of which is covered with felt or wool, or other soft material, which serves as a burnishing pad and also constitutes an air inlet through which air is drawn by means of a fan or other suitable suction device, whereby the surplus powder is raised by suction and passed through a pipe into a trap, filter or other receptacle, and is thus prevented from escaping into the atmosphere.

In the aforesaid apparatus, to insure the steady even outliow from the container, and to drive or carry the bronze powder on to the. work, a portion of the said air under pressure is diverted through a suitable air passage to the lower part of the container. According to the present invention, instead of employing air under pressure, to insure the outflow of the powder from the container, I provide a simple and easily operated device, which is adapted to normally close or cover the outlets in the bottom of the container, but when moved to its open position it simultaneously moves or scoops the bronze powder in the lower part of the container over the said outlets, and forces a portion of same therethrough.

In order that my invention may be clearly understood and readily carried into effect, I will describe `same with reference to the accompanying drawings, in which Figure 1, shows in part sectional elevation,

Specification of Letters Patent.

Serial No. 197,051.

a bronzing head, embodying the features of the present invention.

Fig. 2, shows a sectional plan view, taken on line Af-B of Fig. 1.

Fig. 3,',shows a side and end elevation and a plan view of the cover plate.

Like numerals of reference indicate the same feature or part throughout the several figures of the drawings.

In the bottom of the container 1 is slidably mounted a plate 2 in which is formed a series of transverse holes or slots 3 which correspond in shape and disposition to the outlet holes 4 in the bottom of the container 1. To the said plate 2 is secured a rodi 5 which passes throu 'h the wall of the container 1, and protru es through the hood or cover 6, near the handle or grip part 7 of the bronzing head, at a position where it can be readily manipulated by operators thumb or linger while gripping the said handle of the bronzing head. The outer end of the said rod 5 is provided with a knob 8, between which and the wall of the hood or cover 6, or at other suitable position, is located a spring 9, adapted to move and hold the aforesaid plate 2 in its closed position, that iskwith its holes 3 out of alinement with the holes 4 in the underside of the container 1.

On the upper side of the said sliding cover plate 2, behind each of the holes or slots 3 therein, are fitted or formed plates or pro* jeetions 10, which are preferably disposed in a forwardly inclined direction, and their ends are also bent or curved in a forward direction, thus approximating a somewhat semi-circular formation; the said projections 10 being adapted, on the forward or opening movement of the sliding cover plate 2, to move or scoop forward the bronze powder, and thus positively force a portion through the outlet holes l in the container. The forward or opening movement of the said cover plate 2 may be adjusted or controlled, which in one form may be effected by an adjusting or set screw 11, mounted in the side of the hood 6 and the container 1, its inner end being arranged to impinge against an upturned lug or projection 12 on the said sliding cover plate 2, whereby the holes 3 in the cover plate may be permitted to come into partial or full alinement with the outlet holes 4 in the con tainer, as may be desired; thus controlling the outflow of powder. On the said adjusting` or set screw 11 maybemounted a loclnut 13, whereby it may be locked or secured in any adjusted position.

The cover plate 2 is shown in the drawings as being moved to and held in a forward position, with its holes or slots 3 partially in alinement with the outlet holes 4l in the. container; in which position the outflow of powder would be restricted. It will be readilyl understood that turning or moving the adjusting screw 11 in an outward direction, would Ipermit of the cover plate 2 being moved further in a forward direction, thus bringing the outlet holes 3 into full or complete alinement with theoutlet holes 4 in the container; and that by turning. it inward, the outlets mayl be further restricted, or if desired, completely closed and thek cover plate held or locked in such closed position.

A feature of the present invention is that it permits of bronzing heads constructed in accordance therewith, and. made in various sizes or patterns to suit diferent classes of work, being interchangeable. 'Ihe socket par-t 14', `which is fitted to the handle or stem part 7v of the-hood or cover 6, is of a uniform or standard size, andmay be screw-threaded to receive the screwed end or terminal 15 of thesuction pipe 16; or the said terminals 14. and 15 may be provided with bayonet joint attachment or other suitable form of coulpling device.

Having fully describedfmy invention, what I desire to claim and secure by Letters 'Patent is:

1. In a portable bronzing head having a container provided at its underside with outlets and a pad and also having ahood or cover in spaced surrounding relation to the said "container and also provided at its underside with a pad, said hood providing a space which-opens at the under side of the head andthrough which air maybe drawn byv suction, ay cover plate slidably mounted over s the outlet holes in the bottom of the container, having outlet holes which correspond to those in the container, and provided on its upper side with upstanding projections adjacent its respective outlet holes,

the said cover plate being adapted to normally close the outlets in the container, and when moved forward to open the said outlets and, by means of said projections, to force the powder therethrough'.

2. In a portable bronzing head, in combination, -a container having its bottom provided with outlet holes, a cover 4plate slidably mounted upon said bottom and having outlet holes which correspond to those of the bottoni, said cover plate being provided on its upper side with upstanding' projections adjacent its respective outlet holes and being adapted to normally close the outlets in the container and when moved forward to open the said outlets and, by means of said projections, to force the powder therethrough, an operating rod attached to said cover plate and a spring arranged to move and normally hold said cover plate in its closed position.

3. In a portable bronzing head having a cover plate slidably mounted over the outlet holes in the bottom of the container and provided with holes which correspond to those in the container and having attached thereto `an operating rod arranged to protrude through the' hood or cover which surrounds the container, Aan adjusting or set screw mounted in the hood and container and adapted to engage with a projection on the said cover plate for adjusting or controlling, the movement of same.

4. In a portablenbronzingv head,- in' combination, a container having its bottonrprovided with outlet holes, and a cover plate slidably mounted upon said bottom and having outlet holes which correspondto'those of the bottom, said cover plate* being provided? on its upper side with upsta'nding pro- Y jections adjacent its respective outletv holes and being adapted to normally close the out-l lets in the container and wheny movedf forward' to open the said outlets and,\by means of said projections, to force the pow-'der therethrough.
